Virtualization Technology and On-Demand Computing

In this article from internet.com, Clint Boulton point out the role of virtualization technology as the driver for developing the so called Utility Computing as the paradigm of the next wave in the IT Industry:

"In the last couple of years, utility or on-demand computing has blasted open some doors of opportunity that had been closed by weak spending from a cost-constrained IT sector. One of the ways it has done this has been through a technology called virtualization.

Once largely relegated to the storage space as a way to pool storage from several storage devices into what appears to be a single storage machine, virtualization is gaining steam. Vendors are using it to consolidate massive server workloads, shuttle applications around a network with drag-and-drop ease or just to simplify data-center management."
